If it's really going soft, I'd flush the system and put in new fluid. There may be enough moisture in there to let the mixture boil when it gets hot.
I flushed the system today, and I think you are right. I didn't use brake fluid from an unopened container (I admit I was trying to find some use for the big container I bought and wanted to see if I could get away with an opened container). So I went out to but some new, unopened brake synthetic brake fluid and presto, my problems are solved.

There brakes are solid as a rock and stay solid. Feels like I can stop on a dime and have change to spare.

I went to bleed the rear brakes since I was already bleeding the front, and found some air bubbles. Now the rear almost feels TOO sensitive. I kind of want to bleed some air back INTO the system haha.
